Invention is not limited the shape of shell 7, and the shell of any shape is within protection scope of the present invention.
The 3D display device of the embodiment of the present invention 1 is portable equipment, does not need to use person to hold the 3D display when in use
Device and by the first perforate 71 and the second perforate 72 close to eyes.
Embodiment 2
The difference of the 3D display device of the present embodiment and the 3D display device of embodiment 1 is：Shell 7 is no longer set, and
The composition of image anti-crosstalk structure is different.The 3D display device of the present embodiment also includes：Display panel 1, image isolating construction and
3D imaging arrangements, display panel, the composition of image isolating construction and 3D imaging arrangements and position relationship and all same of embodiment 1,
It will not be repeated here.
As Fig. 2 shows, in the present embodiment, described image anti-crosstalk structure includes：First lens 81, the second lens 82,
One analyzing eyeglass 91 and the second analyzing eyeglass 92.First lens 81 be arranged at the first imaging surface 41 and the first analyzing eyeglass 91 it
Between, the second lens 82 are arranged between the second imaging surface 42 and the second analyzing eyeglass 92.
First lens 81 and the second lens 82 are used for, and form the first virtual inverted image and the second virtual inverted image respectively, and first is empty
Intend inverted image and the second virtual inverted image is superimposed to be formed and invents image planes 10.Invent image planes 10 and be located at lens (the first lens 81 and
Two lens 82) between analyzing eyeglass (the first analyzing eyeglass 91 and the second analyzing eyeglass 92).
The analyzing in the analyzing direction of the first analyzing eyeglass 81 and the first analyzing hole 21 is in opposite direction, the second analyzing eyeglass 82
The analyzing in analyzing direction and the second analyzing hole 22 is in opposite direction.
First analyzing eyeglass 81 and the second analyzing eyeglass 82 can be made analyzing glasses and be worn for user.
First image forms 3D parallax images to rear on the first imaging surface 41, and void is formed further across the first lens 81
The first inverted image intended, equally, the second image forms 3D parallax images to rear on the second imaging surface 42, saturating further across second
Mirror 82 forms the second virtual inverted image, and the first inverted image and the second inverted image form the image pair being superimposed, that is, are formed and invented
Image planes 10.
Because the first image and the second image are the images that have different polarization effect, the polarization direction of the two is mutually hung down
Directly, therefore, the first analyzing eyeglass 81 in opposite direction of the analyzing with the first analyzing hole 21 is set by observing position in left eye, can
To be filtered out eye image using the first analyzing eyeglass 81, that is, filter out and the polarization direction of the first image orthogonal
Two images.Similarly, the second analyzing eyeglass in opposite direction of the analyzing with the second analyzing hole 22 is set by observing position in right eye
82, left-eye image can be filtered out using the second analyzing eyeglass 82, that is, filter out and mutually hung down with the polarization direction of the second image
The first straight image.This makes it possible to realize again to separate left-and right-eye images, the image after separation is connect by images of left and right eyes respectively
Receive, it is then by the aggregation feature of eyes that left-and right-eye images are folded with the retina again, produced by cerebral nerve three-dimensional vertical
The visual effect of body, so as to show 3D stereoscopic picture planes.
In the present embodiment, because the 3D parallax images pair of the images of left and right eyes formed using imaging surface also pass through lens respectively
Superposition formation invents image planes, and reuses analyzing eyeglass and be separated into left-and right-eye images, that is to say, that by the first imaging
The light of the imaging surface 42 of face 41 and second also needs to carry out analyzing processing, therefore, in the present embodiment, by the first imaging surface 41 and the
Two imaging surfaces 42 make non-diffusing reflection face, avoid light from being reflected on the first imaging surface 41 and the second imaging surface 42 to all directions,
So that the first analyzing eyeglass 91 and the second analyzing eyeglass 92 can correct analyzing, ensure 3D rendering display effect.
It should be noted that the 3D display device of embodiment 1 is not suitable for open environment, in addition, the device is hand-held
Equipment, limited by shell, the position relationship between its various components inside is relatively fixed, and is merely able to be micro-adjusted, nothing
Method accomplishes arbitrarily to adjust.And the 3D display device of embodiment 2 is open equipment, suitable for open environment, not by device housings
Limitation, the position between all parts can voluntarily adjust according to being actually needed, and adjustable range is larger.Therefore, embodiment 2
3D display device is bigger relative to the human eye viewing scope of the 3D display device of embodiment 1.
The above-mentioned 3D display apparatus structure of the present invention is simple, without carrying out special processing to film source or image, but directly
Connect and can watch 3D rendering using the present apparatus.
It is understood that the principle that embodiment of above is intended to be merely illustrative of the present and the exemplary implementation that uses
Mode, but the invention is not limited in this.For those skilled in the art, the essence of the present invention is not being departed from
In the case of refreshing and essence, various changes and modifications can be made therein, and these variations and modifications are also considered as protection scope of the present invention.
